William K. (William King) David

Very little firmly documented biographical information appears to survive about this author beyond his published name, Wm. K. (William King) David. He is chiefly known for the 1896 book Secrets of Wise Men, Chemists and Great Physicians, a compact collection of recipes, remedies, chemical preparations, and money-saving formulas.

The book was published in Philadelphia under the name W. K. David and reflects a period when practical manuals mixed household advice, medicine, and small-scale commercial know-how. Today, the work is of interest less as modern guidance than as a snapshot of late-19th-century popular science, home economics, and patent-remedy culture.

Because reliable personal records are scarce in the sources reviewed, details such as his birth, death, education, or wider career could not be confirmed with confidence. What remains clear is that his surviving book preserves the voice of a resourceful, instruction-minded compiler writing for readers who wanted useful knowledge in everyday life.
